Chapter 5. Logging Data
Data logging is one of the PM880’s most powerful and flexible features.
The meter enables you to choose up to 12 measurements to log. Logs can
run one at a time or simultaneously. Error and circular logs are also
available. The logged data is internally stored in battery-backed-up
memory.
A fixed amount of memory is assigned to store logs. The frequency of the
time interval, the length of the log run, and the number of logs affect the
amount of memory required for a particular log. For example, a 2 hour log
that records every 5 seconds will use up more memory than a 2 hour log that
records every 5 minutes.
The PM880 also has various tools to enable the following:
• setting up a new log - page 78
• pausing a log - page 82
• starting and restarting a log - page 83
• ending a log - page 84
• viewing all logs - page 85
• viewing log setup details - page 86
• viewing logged data in graph or spreadsheet format -
page 88
The PM880 has additional logging capabilities. For more details on these
functions refer to Chapter 6, Managing Files and Chapter 7, Using the
PM880 with a PC and Printer.
